Outside water usage for an average consumer in the City of Columbia is around 30% of total water usage. Columbia Water & Light wants to make sure that you know the proper ways to water your landscape to help you save money and conserve water.

Whether you are watering your garden or laying new grass it is important to think about how to use water efficiently. Here are some tips that we think you need to know about how to get the most out of your water and landscape.

Outside water tips:

  • Know how much water your plants need and when to water them to help conserve water.
    • Use regionally appropriate, low water-using and native plants.
    • Avoid watering in the middle of the day when the hot sun will evaporate much of the water before it can get too thirsty plants.
    • Lawns only need up to one inch of water a week, including rainfall.
      • Shrubs, trees, and other perennials generally will need even less because of their deeper root structure.
  • Set your irrigation system correctly to avoid water waste
    • Water is wasted by poorly designed and neglected sprinkler systems that spray sidewalks, driveways, and the street.
  • Schedule each individual zone in your irrigation system to account for the type of sprinkler, sun or shade exposure, and type of plants and soil in the specific area.
    • The same watering schedule rarely applies to all zones in the system.
  • Install a microirrigation system for gardens, trees, and shrubs.
    • Microirrigation applies water slowly and directly to the plants’ roots to minimize evaporation, runoff, and loss to the wind.
